I've been trying to optimize my spending on these case opening sites, and I've noticed that they often offer promo codes. However, figuring out the best way to use them is tricky. Some seem to be percentage-based, while others give you a fixed amount of bonus cash. Does anyone have a good strategy for using promo codes on case opening sites to maximize their value? Is it better to save them for larger deposits, or use them on smaller ones to spread the bonus out? What's worked best for you?
